Dolly Parton fans eager to purchase her latest album, 'Blue Smoke' when it is released next week have even more reason to be excited. The songstress has announced she is adding a few bundles for anyone who pre-orders the record before its May 13 release date.

“I really wanted to do an album that had all the colors of my whole career,” Parton explains.

“We have some bluegrass stuff, some gospel flavored things, and we have some mountain style stuff. We also did a cover of Bon Jovi’s ‘Lay Your Hands On Me’ as a gospel song, and it’s absolutely great. We did a cover of Bob Dylan’s ‘Don’t Think Twice,’ which has always been a favorite of mine. We did it the Americana way, with plucking guitars and finger-picking and bluegrass harmonies."

She adds, "I love choosing other peoples’ songs, doing some covers. It was really a special album to do. It was fun to do.”

A special video message from the 68-year-old, along with a sampling of four exclusive tracks, is available at Walmart.com. The four bonus tracks available exclusively through Walmart are 'Get Up Get On Get Out,' 'Olive Branch,' 'Early Morning Breeze' and 'Angels In the Midst.' Fans who purchase the album through the store's website will also receive a digital copy of the record for free.

The Tennessee native has already sold thousands of copies of 'Blue Smoke,' thanks to a recent appearance on the shopping network QVC. Parton added five bonus tracks for fans who purchased 'Blue Smoke' in her one-hour special, which featured live versions of some of her classics, including '9 to 5,' 'I Will Always Love You,'  'Jolene,' 'Two Doors Down' and 'Here You Come Again.' That bonus package is still available for purchase here.

Three different bundles are also available at Parton's website. Options include the CD with a commemorative laminate with lanyard, the CD with a t-shirt, mudflap, key chain and mug, and a special bundle, only available to 25 people, with everything previously listed, plus an autographed vinyl copy of 'Blue Smoke' and a limited edition Parton lithograph.

'Blue Smoke' will also be available for download here.

The United States leg of Parton's Blue Smoke World Tour will kick off on May 22 in Tulsa, Okla. See a list of all of her upcoming shows here.
